Description
Technical field
The present invention relates to a kind of fire plant class technical field, especially a kind of firefighting fan supercharging device.
Background technology
Dense smoke, toxic odor distribute slowly in fire rear chamber, are brought quite for search and cleaning work after fire fighter's calamity
Big inconvenience is generally divulged information with powerful firefighting fan, still, the motor that the wind pressure of conventional firefighting fan is equipped with by wind turbine
Power and determine air volume and range, fixed wind turbine can only also play intrinsic air quantity and range, in very big degree
On cannot make firefighting fan play bigger efficiency and range.
The content of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, a kind of firefighting fan supercharging device is provided, including
Firefighting fan, isometry block, supercharging are covered, and the motor lower end in firefighting fan sets supporting support, both ends and respectively sets connecting flange one, lower end
If bottom plate, bottom plate lower end sets several isometry blocks, the air opening end connection supercharging cover of firefighting fan, and supercharging is provide with the supercharging of cone
Taper Pipe, supercharging Taper Pipe bigger diameter end try it is blue, interior set taper hole, the major diameter of taper hole and the air outlet of firefighting fan are docked and connected, this hair
It is exported after the moving air compression supercharging that bright supercharging cover can export firefighting fan, greatly increases the air quantity lift of firefighting fan
And kinetic energy, improve fast cooling effect and smoke exhaust efficiency.
In order to achieve the above objectives, the present invention provides a kind of firefighting fan supercharging device, including firefighting fan, isometry block, increasing
Pressure cover, the motor lower end in the firefighting fan set that supporting support, both ends respectively set connecting flange one, lower end sets bottom plate, the bottom
Plate lower end sets several isometry blocks, the air opening end connection supercharging cover of firefighting fan, and the supercharging is provide with the supercharging Taper Pipe of cone,
The supercharging Taper Pipe bigger diameter end try it is blue, interior set taper hole, the major diameter of the taper hole and the air outlet of firefighting fan are docked and connected.
The flange and the connecting flange one of firefighting fan the air opening end connecting hole one that be all provided with position identical.
It sets up defences in the firefighting fan shield.
The beneficial effects of the invention are as follows：After the moving air compression supercharging that the supercharging cover of the present invention can export firefighting fan
Output greatly increases the air quantity lift and kinetic energy of firefighting fan, improves fast cooling effect and smoke exhaust efficiency.
Description of the drawings
Fig. 1 is the schematic diagram of the present invention；

In figure：Firefighting fan 1, connecting flange 1, connecting hole 1, motor 102, protective cover 103, bottom plate 104,
Supporting support 105, isometry block 2, supercharging cover 3, flange 301, supercharging Taper Pipe 302, taper hole 303.
Specific embodiment
As shown in Fig. 1~Fig. 2：The technical solutions of the present invention will be further described, a kind of firefighting fan supercharging
Device, including firefighting fan 1, isometry block 2, supercharging cover 3,102 lower end of motor in the firefighting fan 1 set supporting support 105,
Both ends respectively set connecting flange 1, lower end sets bottom plate 104, and 104 lower end of bottom plate sets several isometry blocks 2, firefighting fan 1
Air opening end connection supercharging cover 3, the supercharging cover 3 set the supercharging Taper Pipe 302 of cone, and supercharging 302 bigger diameter end of Taper Pipe is set
Flange 301, it is interior set taper hole 303, the major diameter and the air outlet of firefighting fan 1 of the taper hole 303 are docked and connected, supercharging of the invention
It is exported after the moving air compression supercharging that cover can export firefighting fan, greatly increases the air quantity lift and kinetic energy of firefighting fan,
Improve fast cooling effect and smoke exhaust efficiency.
The flange 301 and the connecting flange 1 of 1 air opening end of the firefighting fan connecting hole one that be all provided with position identical
1011。
It sets up defences in the firefighting fan 1 shield 103.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, the change or replacement that can be readily occurred in,
It should be covered by the protection scope of the present invention.
